What is "s.e.x."

"S.E.X." is the first single by Lyfe Jennings from his second album The Phoenix. The song is about young teens losing their virginity from pressure. The song features R&B singer Yolanda "La La" Brown.

"S.E.X." debuted on the Billboard Hot 100 chart at number 99 and slipped off just to re-enter the following week again at number 99. It eventually peaked at number 37, making it Lyfe's (and Lala's) most successful single. "S.E.X." was a top-five hit on the Billboard Hot R&B/Hip-Hop Songs chart and received strong airplay on BET and some airplay on radio and MTV.
